G. 757) The invention described herein may be manscope is associatedwith a traversing mechanism ufactured and used by or for the Government for consisting of an arcuate rack 8 fixed on the governmental purposes, without the payment to under side of the telescope and an operating shaft me of any royalty thereon. 9 carried by the support.

5 This invention relates to a sight for ordnance. A reflecting member such as a mirror I is In providing sights for artillery, it has been positioned in front of the telescope and across customary for many years to employapanoramic the axis thereof and is carried on a base ll telescope of the periscopic type so that the obwhich is rotatably mounted in an opening I2 server could employ an aiming point which was of the support 5 and has an annular flange l3 located in any direction. However, in actual resting on the support. The base is provided 10' practice an aiming point is never selected to the with a worm wheel M which is engaged by a rear of the observer because of interference on worm IS on a shaft l6.
